How High School Semesters Work
In most US and Canadian high schools, your academic year is broken into two semesters. Each semester is usually treated as a "Clean Slate" for your GPA.
A typical semester consists of two quarters (or terms) and one big exam at the end. The school assigns a specific "Weight" to each part.
The 40/40/20 Rule
This is the most common weighting system used in schools:
- Quarter 1: 40% of Semester Grade.
- Quarter 2: 40% of Semester Grade.
- Final Exam: 20% of Semester Grade.
This system puts huge pressure on consistency. You cannot fail both quarters and expect to "Ace the Final" to pass the class. The math simply doesn't work.
Scenario: Can I Still Get an A?
Let's say you slacked off a bit.
- Q1 Grade: 85% (B)
- Q2 Grade: 88% (B+)
- Goal: 90% (A) for the Semester
The Math:
Locked points: (85 * 0.4) + (88 * 0.4) = 69.2 points.
Points needed: 90 - 69.2 = 20.8 points.
Final Exam Needed: 20.8 / 0.2 = 104%.
Cumulative GPA vs. Semester GPA
It is important to understand how this grade fits into the bigger picture.
- Semester GPA: The average of your grades just for this 5-month period.
- Cumulative GPA: The average of ALL your semester grades from Freshman year to Senior year. This is the number colleges look at.
A single bad semester won't destroy your Cumulative GPA, but a string of bad semesters will.
College Variations
Universities often don't use Quarters. They use a simple Midterm/Final system.
| System | Weights | Note |
|---|---|---|
| Standard HS | 40% / 40% / 20% | Consistent effort required. |
| College A | 30% Mid / 40% Final / 30% HW | Exams are everything. |
| College B | 50% Mid / 50% Final | High risk. No buffer from homework. |
